摘要： A fuel adsorption layer formed in a canister is partitioned into an upper adsorption layer and a lower adsorption layer by a partition plate in which a heater is embedded. The relation between a heating value of the heater and thickness X of the upper and lower adsorption layers is set so that the temperature of a part closest to the heater heating face of the fuel adsorption layer is lower than a fire point of the fuel, and the temperature of a part farthest from the heater heating face is higher than the boiling point of the fuel. With the configuration, by heating the fuel adsorption layer by the heater, the desorption performance of activated carbon is improved, and almost all of the fuel vapors adsorbed can be desorbed.

摘要： An absorbent, such as, for example, an active carbon, is provided in an intake air passage, for example, in an air cleaner, to efficiently adsorb fuel vapor. To ensure that fuel vapor adsorbed into the intake air passage can be efficiently desorbed even when there is only a small amount of the intake air, an intake throttle valve is provided upstream of the adsorbent and an opening of the intake throttle valve is throttled so as to decompress an area near the adsorbent. Desorption of fuel vapor also can be efficiently promoted by using a heater to directly heat the adsorbent in the intake air passage or by heating the intake air to indirectly heat the adsorbent.

摘要： A shut off valve is provided in an intake line farther upstream than a throttle valve of the intake passage and farther downstream than an air cleaner. This shut off valve is opened by a signal or the like from an ECU when an engine is operating. Further, the shut off valve closes when the engine is stopped so as to suppress evaporative fuel inside the intake passage from flowing outside through the air cleaner. The evaporative fuel trapped inside the intake passage passes through a bypass passage that provides communication between the intake passage and the canister, and is then adsorbed with an adsorbent in the canister. A blow-by passage is also connected to the intake passage that is closed off by the shut off valve. Because the blow-by passage is closed off by a blow-by valve, which is closed during normal operation when the engine is stopped, sticking of the shut off valve and the throttle valve and the like due to the inflow of blow-by gas into the intake passage is inhibited.

摘要： A fuel vapor handling apparatus supplies a purging air to a canister by using a purge pump and purges fuel desorbed from the canister into an intake pipe. A controller intermittently operates the purge so that the canister internal temperature recovers from a reduced level caused by the latent heat of vaporization of fuel during an operating period of the purge pump. Therefore, desorption of fuel from the canister during an operating period is facilitated. Since the actual operating time of the purge pump is reduced, the life of a motor that is a power unit of the purge pump becomes longer.

摘要： An intake device for an internal combustion engine has: a first intake pipe which is connected to the engine so as to conduct an intake air to the engine, and which has an opening portion that is provided in an upstream-side lower portion of the first intake pipe located at an upstream side in a flowing direction of the intake air; and a second intake pipe which has a downstream-side end portion that faces an upstream-side end portion of the first intake pipe, with a gap formed therebetween, and which conducts the intake air to the first intake pipe. An unburned gas reflux passage is provided for conducting an unburned gas from the engine to the first intake pipe. A container surrounds the gap and the opening so as to receive the unburned gas flowing from the opening portion. Thus, it becomes possible to prevent release of unburned gas into the atmosphere by performing a simple process on a conventional structure.

摘要： A throttle valve is opened after stopping an engine to prevent the valve from sticking. Then, when a temperature of the valve has become lower than the polymerization temperature, the valve is closed to seal the vapor of the HCs in a surge tank downstream. Changes in the temperature of the valve are, for example, estimated based on a temperature of an intake air detected by an intake temperature sensor.

摘要： An HC adsorbing sheet inside an air cleaner is disposed such that a large amount of activated carbon is contained on the side of an engine and that a small amount of activated carbon is contained on the other side of the engine. Thus, the HC adsorbing sheet can efficiently adsorb evaporative fuel. That is, by changing the amount of activated carbon contained in accordance with differences in concentration of evaporative fuel, it becomes possible to prevent the pressure loss in an intake system from increasing. On the other hand, one end of a second intake pipe extends to a region where the amount of activated carbon contained in the HC adsorbing sheet is large, whereby it becomes possible to concentratively supply activated carbon with intake air in the region where the large amount of activated carbon is contained. Therefore, the efficiency in purging evaporative fuel can be prevented from declining.
